To all whom it may concern:

Be it known that I, JOHN C. DE LANEY,

V a subject of the King of Great Britain and molding to drop below itsIreland, residing at Watertown, in the county of Middlesex and State ofMassachusetts, have invented certain new an useful ImprovementsinWoodworking Machinery, of which the following is a specification,reference being had thereinto the accompanying drawings.

The principal object of my invention is to provide means whereby each ofseveral strips of molding being simultaneously made out of a piece ofstock, may, throughout every portion of its length, be subjected touniform conditions at the molding head of the machine, so that whenfinished, it is exactly of the same size and quality of finishthroughout its length. After the strips have begun to be formed and thefree ends emerge from the machine, the end portions, if they are notcontrolled, will move'capriciously; some may approach each other,thereby causing one or more 0 the saws to bind, to become heated, andburned; should they happen to be supported bythe top of a table whichwas below the plane of the bottom of any one or more of the strips ofmolding formed, then, the weight of so much of each molding as has beenformed out of the stock being worked up, would tend to cause the bottomof the plane in the machine, hence the thickness of the molding would becorrespondingly reduced; and vice versa, should the 1 table top be abovethe bottom plane of themolding, the molding would be thicker thanintended. Also, if each strip were of difi'erent thicknesses, and thetable top were of the right height for one strip, it would not be 'foranother. Further, if the table be too far away from the molding heads,the strips will vibrate and chatter, and will interfere with thesuccessful operationof the molding head.

Now the feature of my invention which will obviate these objections,resides in" adjustableguiding and supportingdevices for compelling everyportion of each strip to move away from the molding head in the samestraight line in which it moves into plpegative engagement with themolding In the drawings illustrating the principle I of -my Inventionand the best known method may, to exactly the same its entire length,thereis provided now known to me of embodyingthe same in operativestructure, Figure 1 is a perspective view showing my invention embodiedin a molding machine, only a portion of which is illustrated; and also amethod of working up stock into various forms of molding strips. Fig. 2is an end.

perspective view showing my pivoted supporting bracket being droppeddown out of normal position, to permit the swinging forward and back ofa pivoted arbor, with molding heads and saws thereon. Fig. 3 is anelevation of the.pivoted supporting bracket with various adjustingmeans. Fig. 4 is a plan of what is shown in Fig. 3; the arbor havingbeen removed from the boxes. Fig. 5 is a perspective view of a framehaving mounted-therein guiding and supporting T-blocks and sawfollowers, corresponding to the saw cuts and molded surfaces in theseveral strips being formed out of a piece of stock; also a detailshowing one of thelock blocks for securing the T- f blocks and sawfollowers in the frame.

6 is a perspective view of one of the blocks; While Fig. 7 is a similarview of one of the saw followers. In order that each during itsmanufacture, be subjected conditions throughout a bracket table40,Figs.1, 2, 3 and 4, movably mount.- ed on the frame of the machine bypivots 41, Fig. 3, so that the table may be dropped down and notinterfere with the swingmg of a pivoted arbor 28, Fig. l, for suitablemolding'heads B and saws C. This arbor although shown herein, andclaimed by me in my application for United States Letters Patent, SerialNo. 689,103, filed April 8, 1912. 2130 hold'the table 40 up in normalposition, a lock slot 42, Figs. 1, 2 and 3, is provided in each of thearbor boxes 2, 3, and a corresponding slot 43 in each end of the table,whereby a bolt 44 and-nut 45, engaging these slots, may be tightened'tofirmly secure the table in operative position. I

Mounted in vertical slots 46, Fig. 2, in the table is an adjusting bar47, adjusted vertically by adjusting screws 48, Fig. 3, assing throughbosses 49 on the inside 0 the table, and engaging the under side of thebar; while resting upon'the bar, is a frame 50 slidable horizontallytoward or away strip of molding, as D,

is fully described from the molding heads upon the arbor,

and capable of being fixed in any desired posit-ion, by means of bindingbolts 51 engaging suitable parallel slots 52 in the frame. On the'topsurface of this frame 50 and parallel with the axis of the arbor is aretaining member 53, Fig. 5, having a lock slot 54 into which may beslid metal T- blocks 55, Fig. 6, and saw followers 61, Fig. 7; theT-blocks having secured to their top surfaces, Wooden or metal blocks56, each having its top surfaces in counterpart with those of themolding made by its respective molding head, as shown in .Figs. 1 and 3;and the saw followers being of the same gage as the saws. Two lockblocks 57, Figs. 4 and 5, confine these IT-blocks and saw followers inthe retaining member 53:

and the lock blocks, T-blocks, and saw fol lowers are all bound togetherand adjusted in the right position transversely, and relatively to themolding heads and saws upon the arbor, by means of adjusting screws 58,

in opposite sides of the frame, and having their points engage cavities59 therefor in the outside surfaces of the lock blocks 57, Fig. 5.

'lhe molding heads and saws shown, and forming no part offmy presentinvention, may be like those described and claimed in United StatesPatent No. 999,014, granted tome July 25, 1911, and they may be securedthereon as described therein.

lhe stock to be cut up into strips of molding, and the number of stylesof strips to be made, having been determined, suitable heads B and sawsC are selected and mount ed upon the arbor 28, in the way pointed out inmy said application Serial No. 689,103, of which the presentapplication'is a division. Next, the bracket table-40 is lifted up aboutits pivot 41, Figs. 3 and 4, and secured in horizontal position by thelock'bolts 45 in the lock slots 42, in the boxes, engaging the lockslots 43 in the table. Proper molding supporters 56 and saw followers 61are then slid into the T- slot of the retaining member 53, Fig. 5, andthere secured in the corresponding vertical planes of the molding headsand saws, by means of thelock blocks 57 and the adjust- .ing screws 58.To raise or lower the sup-' porters from one horizontal plane toanother, the adjusting bolts 48 controlling the vertical movementsof'the bar 47 in the slot in the bracket are operated. The frame 50 maybe pushed in a horizontal plane as close to the heads and saws as willprevent chattering of the strips, and yet will notcause interferencewith the heads and saws, and be there secured by the bolts 51 engagingthe lock slots 52 in the frame; the pressure bars, not shown, are thenadjusted in the usual manner to hold the stock down upon the moldingheads as it passes over them.

It will now be plain, that by compelling the holding a molding stripdown upon a molding head; a support having a supporting surface, acounterpart of the molded surface of the strip; means for adjusting thesupport vertically; means to adjust the support horizontallytoward oraway from the molding head; means for adjusting the sup-' port parallelwith the axis of the molding head.

2. A table member; a molding support, movably mounted in the table andcomprising a block having its top surface a counterpart of that of themolding to be supported a saw follower nextto said block; means forbinding them together; means for adjusting them transversely, inrelation to the table. Y 3. A'bracket pivoted to a molding machine; atable movably mounted in the bracket; a supporting block and a sawfollower movably mounted in the table; means to adjust, in thehorizontal plane of the bracket, the table. toward or away from thecutter of the molding machine; means for securing the supporting blockand saw follower together; means for adjusting vertically, the' table inrelation to the bracket.

In testimony whereof I afiix my signature in presence of two witnesses.
